Wales began the second day of the London Sevens at RFU headquarters with what was always going to be a difficult tie against an Argentina side at near full strength. Fifteen months ago, the two sides met in the final of the Rugby Sevens World Cup in Dubai and as history has recorded it was Wales who triumphed.
In London, however, it was Argentina who looked the sharper and more aggressive, with a second-half performance that killed off Welsh hopes of a win.
Wales led 14-12 at the break with tries from Ifan Evans and Rhys Shellard, both converted by Gareth Davies, but from the second-half kick-off the Pumas turned the screw, taking the lead with a try from Diego Palma and then widening the gap with a rare penalty goal from Joaquin Todeschini for a 20-14 lead.
Then when Nicolas Bruzzone breezed crossed for a try, it was all over for Wales, the final score being 27-14 to Argentina.
The result meant that Wales went into the semi-final of the Plate and a difficult tie with Fiji, who had earlier lost to Australia 29-28 and had something to prove to their fans.
In the event the pacific islanders did just that with a dazzling display of running and supporting skills to score three tries, two by Apisai Naiyabo and one by Seremaia Burotu in the first half for a 15-0 lead at the break.
Fortunately for the game and for their own confidence, Wales were able to break the Fijian defence with clever handling that resulted in a try for Lloyd Williams. But it only stirred the Fijians into scoring mode once more, producing a converted try for Randall Kamea and a 22-5 lead.
As full time approached, Wales found the strength to launch an attack that finished with Williams crossing for his second try and a final scoreline of 22-10.
Overall, Samoa extended their lead over New Zealand in the race for the World Series title although neither reached the Cup Final. That was contested between Australia and South Africa with the Wallabies emerging winners by 19-14.
